I offer the analogy of attempting, possibly half a century ago, to persuade an Apartheid supporting South African, or a Ku Klux Klan group in the Deep South, to believe that black and white skinned people were absolutely identically equal human beings.
So...what are the most empowering and equal of entertainments? What about having clubs for white customers to drink and gamble on the outcome of savage fights between the exhibited black men, encouraged to fight degradingly, maybe to serious injury, incentivised by the unusual ability to earn good money, because in the way the rest of their society is arrange, they have little or no equal opportunity to earn in the same way as whites?
Would that make those whites start to respect all black skinned people as equals, treat them well, pay them fairly, employ them on the same basis as their own friends and family? If not, what would?
Let white customers go to another club to drink and order naked black women do various sexual acts? No? Still not empowering or equalising, and still not making for a mixed-race society with equality of respect, opportunity and pay?
Certainly, the maimed black skinned survivors of the fight-to-the-death clubs would have adjusted their mind-sets to approve what was bringing them a good income, where nothing else would. So would the naked black skinned sex workers. They would not want the income stream stopped, any more than the club owners and white customers would. You would easily find them arguing that their work was somehow a good thing, since they all need to convince themselves of what they know to be a lie.
